With its 173 square kilometres, (67 sq. mi.), the city of Narbonne boasts not only the largest city territory of the department but also the most diverse.
Centred on the lower Aude valley, the city extends along its East-West axis from the Mediterranean Sea to the coastal buttresses of the Corbières Maritime Mountains, encompassing the La Clape limestone range.
From North to South, it stretches from the Aude's current course to the edges of Sainte-Lucie Island, including more than half of the Bages-Sigean lakes.

Located on the coast of one of the most popular tourist regions, Narbonne enjoys the many advantages of a seaside resort with a 5-kilometer (3-mile) beach and a marina. At the same time, it prides itself on an urban centre resonating with history (cultural sites, museums, Canal de la Robine…). These attractions all nestle in an extraordinary environmental setting (La Clape limestone range, vineyards, lakes…) at the heart of France's 51st Regional Natural Park.

The city is also a hub of utmost geographical importance, where roads, railroads, and highways have to converge.

The city offers all the necessary infrastructure to welcome and accommodate tourists: the Tourist Office (Office de Tourisme), rated 2 stars (place Salengro, +33 4 68 65 15 60).

These features all contribute to Narbonne's prestigious role as a major tourist destination of the Languedoc-Roussillon.
